Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Plano Owner’s Guide

We stock and install Famco-compatible flue liner replacement in Plano, with typical installed pricing running $1,800-$3,400 depending on diameter, height, and whether the connection to the appliance collar needs reworking. Most Famco liner jobs we book are completed same-day once the model is verified, and we carry common diameters from 5.5″ to 8″ on our trucks. Most Plano homeowners discover their Famco flue liner has failed during a routine sweep when the camera reveals cracked refractory segments, or they notice water staining on the firebox after rain - a sign the liner’s top joint has separated and is letting condensation run down the flue wall.

Which Famco Models This Applies To

Famco built two main liner series that remain in Plano homes: the older Famco 3000 series (discontinued roughly 2012) and the Famco Pro-Flex line that replaced it. The 3000 series used a heavier-gauge 316Ti stainless with a distinct ribbed collar at the top termination; Pro-Flex switched to a smoother wall profile and a different clamp-style connection at the appliance adapter. Both carry the Famco name stamped on the top termination plate, visible from the firebox with a flashlight.

The compatibility gotcha we see most in Plano is the 3000 series 6″ liner that measures 6.25″ actual outside diameter - it won’t accept standard 6″ Pro-Flex replacement sections without a stepped adapter we fabricate on-site. We source both OEM Famco segments through Haven’s buying network and quality aftermarket equivalents from Olympia Chimney when the OEM lead time stretches past what a heating season allows. For most Plano homeowners, the aftermarket equivalent carries the same 20-year warranty and installs identically; we note the origin on your written scope so there’s no confusion about what you’re paying for.

Signs Your Famco Flue Liner Replacement Is Failing

• Water stains on the firebox floor or smoke shelf. Famco top terminations use a slip-fit joint that can work loose after years of expansion cycles. Once the seal fails, Plano’s spring storms drive water down the flue. The camera shows rust streaking on the liner wall and often spalling on the rear firebrick.
• White efflorescence blooming on the exterior chimney brick. This means flue gases are leaking through liner cracks and condensing in the chimney cavity. The salts migrate outward. In Plano’s clay-heavy soils, this accelerates freeze-thaw damage if the cavity stays wet through our occasional hard freezes.
• Smoke rollout when opening the firebox door. A Famco liner with separated segments or a collapsed joint reduces draft capacity. The flue can’t establish enough negative pressure to pull combustion air up, so smoke spills into the room on cold starts.
• Chunks of refractory material in the cleanout or firebox. The Famco 3000 series used a cast refractory liner in some factory-built fireplace installations. When it fails, pieces detach and fall. This is beyond patching - the liner has lost structural integrity and needs full replacement.
• Carbon monoxide detector alerts near the fireplace. Any liner breach is a potential CO pathway into living space. This symptom means stop using the appliance immediately and call for inspection. We treat these calls as priority and run the camera same-day when possible.

Replacement Cost & What’s Included

What drives the range: liner diameter, total linear feet from firebox to termination, and whether we need to drop the existing chimney cap or rebuild the crown to accommodate a new top plate. Every Plano job gets a written price before work starts - Haven Standard Clause 1 - with the scope, materials list, and warranty spelled out. The liner itself carries a 20-year manufacturer’s warranty; our installation workmanship is covered by the 365-Day Done Right Promise.

DIY or Call Us?

There’s no safe DIY path for flue liner replacement. The work involves working at height on a pitched roof, handling sharp stainless edges, and - most critically - verifying proper draft and clearance to combustibles once installed. An improperly seated liner can overheat adjacent framing; a gap at the appliance connection can spill carbon monoxide. We’ve inspected three Plano homes in the past two years where a homeowner-installed liner missed the collar by half an inch and was dumping exhaust into the wall cavity.

What you can safely check: shine a flashlight up the flue and look for visible cracks, gaps at joints, or debris that shouldn’t be there. Note the model number on the termination plate if you can read it. Then call us with what you found. We’ll run the camera, show you exactly what we’re seeing, and give you a written price before any work starts. Call (469) 240-3101.
